I don't know if this is possibly relevant,
While working on my jca/jdbc Firebird driver I experienced:
with read committed isolation, got a very similar error (couldn't transfer
-50.0), caused by deadlock exception in database. It occured 2 times,
once/ multithreaded test.
with snapshot (more or less serializable) isolation I did not get this
exception.
This seems kind of odd to me, isn't jboss supposed to be locking all the
beans in a transaction for serializable access? If so how can a db deadlock
occur?
Unfortunately to the likelyhood of current relevance, I am still using an
old 2.3 beta.
